Kettler is stepping down to spend time with his numerous activities in the Austin, Texas, area, according to multiple sources familiar with the situation, and the move isn't part of Dell's reorganization activities.

On Wednesday, shortly after this story was posted, Dell spokesman David Frink confirmed Kettler's departure.

"He wants to take time to focus on his family and his many other varied interests beyond Dell," Frink said. The retirement will take place "in the next few months," and Dell declined to comment on any plans for a new CTO.
